How to get type backbone model?

Question

I am learning backbone now. And I have a problem like this: can I get type backbone model. Backbone have a function like typeof in javascript or instanceof in java. Like that:

getModelTypeot: function(model) {
    // return model type 
} 

Answer 1

In JavaScript each object has a reference to its constructor (a function that was used to create the object). It's accessible as obj.constructor.

If you have a Backbone.js model, which is extended from Backbone.Model in this way: var YourModel = Backbone.Model.extend({});, you could create an object using new: var yourModel = new YourModel();.

Then, you could use yourModel.constructor:

yourModel.constructor === YourModel // true

Or instanceof:

yourModel instanceof YourModel // true
yourModel instanceof Backbone.Model // true
